LF398N/NOPB  

OP Amps, Buffer Amps ICs

The Texas Instruments LF398N/NOPB is a low-power, dual operational amplifier (op-amp) that is designed for a wide range of applications. It is a member of the LF398 series of op-amps, which are known for their low power consumption and high performance.

Description:

The LF398N/NOPB is a dual op-amp that is available in an 8-pin DIP (dual in-line package) or an 8-pin SOIC (small-outline integrated circuit) package. It is designed to operate over a wide range of supply voltages, from ±2.5V to ±18V, and has a quiescent supply current of only 2.4 mA per amplifier. This makes it well-suited for battery-powered applications where low power consumption is critical.

Features:

Some of the key features of the LF398N/NOPB include:

1. Low power consumption: The LF398N/NOPB has a quiescent supply current of only 2.4 mA per amplifier, which makes it ideal for battery-powered applications.
2. Wide supply voltage range: The LF398N/NOPB can operate over a supply voltage range of ±2.5V to ±18V, making it suitable for a wide range of applications.
3. High input impedance: The input impedance of the LF398N/NOPB is very high, which means it can accept signals from sources with high output impedance without significant loading.
4. Low output impedance: The output impedance of the LF398N/NOPB is low, which means it can drive loads with low impedance without significant loss of signal strength.
5. Short-circuit protection: The LF398N/NOPB has built-in protection against short-circuit conditions, which can help prevent damage to the op-amp in the event of a short circuit.

Applications:

The LF398N/NOPB is a versatile op-amp that can be used in a wide range of applications, including:

1. Audio amplification: The LF398N/NOPB can be used in audio amplifiers to provide high-quality amplification of audio signals.
